What to do when eBay limits are exceeded?
Every eBay seller has a specified monetary value and an item count every month that is set automatically. Both active and sold listings count toward the monthly limit.
To view your current monthly limit, head to your Seller Hub, open the Overview page, and scroll to the Monthly limits section:
When trying to send an item to eBay over the limit, it will remain in an error status in the Selling List. You might find this error in the logs:
This listing would cause you to exceed the amount you can list. You can list up to $16.84 more in total sales this month. Please consider reducing the starting price or request to list more: https://ilowebapp.ebay.com/ilo/portal
Salestio offers a workaround in the Global Profile settings. Go to Profiles > Global Profiles and select yours. In “Item QTY Mode” select “Not more than”. This mode will keep updating the item count on eBay while keeping it under “Item QTY Value”. We will set it to 4 for our store.
An example of this configuration: items that have 2 or 3 in stock will have the same value on eBay. At the same time, items that have 6 or 25 stock will be listed with just 4.

After making the changes, go back to the Selling List and send the item again. Now, the items will be posted to eBay with limited stock.
